Engagement rate by impressions (engagements ÷ impressions × 100).
carouselmaker.comFormat is the biggest lever you have on LinkedIn. The chart above shows why. Carousel (document) posts get the highest engagement of any content type, averaging 7.00% engagement by impressions against about 5.20% across all formats (Social Media Examiner, 2026). Carousels also grew faster than any other format last year, up 14%. Every number here uses the same calculation: engagements divided by impressions, times 100.
Engagement rate by post format
The ranking holds up across studies. Carousel and multi-image posts sit at the top (7.00% and 6.45%), with video close behind at 6.00%. The formats that ask the least of the reader sit at the bottom: plain text (4.50%), polls (4.20%), and links (3.25%). Link posts come last, which fits what most marketers already suspect. LinkedIn limits the reach of anything that sends people off the platform.
The exact percentages move around depending on who is measuring, since every tool samples different accounts and counts engagement a little differently. The order rarely changes, though. Some studies put the gap even wider, with carousels pulling several times the engagement of text-only posts. Treat the bigger multipliers as rough rather than precise.
Why carousels win
It comes down to attention, which is what the algorithm rewards. Swiping counts as engagement, and every slide a reader swipes through adds to the time they spend on your post. That dwell time is one of the strongest signals LinkedIn uses to decide who else sees it. A good carousel can earn several interactions from one reader before they even react.
- Multi-slide posts hold attention longer than a single image or a block of text.
- People save and resend carousels they find useful, and LinkedIn weighs those actions heavily.
- Eight to twelve slides give you room to make a full point, so the post stands on its own.
- Documents keep readers on LinkedIn, while link posts that push people away get throttled.
What counts as a good rate?
Compare your own posts against the 2026 benchmarks below. A carousel above the 5.20% platform average is doing well. One at or above the 7.00% carousel average is in the top tier.
| Platform average (all formats) | 5.20% |
| Document / carousel average | 7.00% |
| Best-performing format | Document / carousel |
| Lowest-performing format | Article / link (3.25%) |
| Engagement basis | by impressions |
How to hit those numbers
- Open with a hook. The first slide decides whether anyone swipes, so lead with a bold claim or an open question.
- Put one idea on each slide. A reader should get it in about two seconds on a phone.
- Design for 4:5 portrait (1080x1350). It takes up the most room in the mobile feed. Square (1:1) also works.
- Keep it to eight to twelve slides, and end with a clear call to action.
- Export the slides as a PDF and upload it as a document. LinkedIn turns it into a swipeable carousel.
A couple of our tools help with production. The carousel size guide has the exact dimensions, and the LinkedIn post formatter cleans up the caption you post alongside the document.
